Python 3.5和请求模块的许多错误

Question

所以我知道下面会看到很多代码，但我绝对难以接受，因为我在使用python时从未遇到过这样的问题。

我希望使用请求模块来帮助我加快一些基于Web的工作。我根据开发人员的要求下载了zipball并运行了＃34; setup.py＆＃34;将它安装到＆＃34; site-packages＆＃34;目录。

我已经验证了所有内容确实应该在哪里，理论上我应该能够导入它然后使用它，但是当我输入任何代码来创建新请求时，例如：<登记/> r = requests.get（＆＃39; https://api.github.com/events＆＃39;） 我在下面得到了大量的错误，我不明白这一点。

Answer 1

我回答了我自己的问题，因为我在URLLIB3和Python 3.5请求的文档中做了更多的挖掘，发现根问题是WIN错误10061.

URLLIB3和Requests从Internet Explorer的默认代理设置中获取其设置。

通过将我的Internet Explorer代理设置重置为空，它解决了我的所有问题。

出于某种原因，即使我从未在这台机器上使用过Internet Explorer，除了下载firefox，我使用的其他一些应用程序必须更改IE中的设置。可能是Windows防火墙。

希望将来出现的任何人都会看到这个问题并从我的错误中吸取教训。

Answer 2

很明显，您遇到了连接问题。不知道更多，我猜这是由于代理问题。如果是，请stackoverflow answer设置requests模块的代理。

如果没有，1）操作系统是什么？，2）为pip设置环境变量？ 3）企业网络还是家庭？

Answer 3

确实，问题出在 Internet 设置上。如何修复：

1. 点击右上角的齿轮
2. 选择一项“Internet 选项”
3. 转到“连接”标签
4. 点击“局域网设置”
5. 取消勾选“使用代理服务器...”
